- A water and power utility moved SCADA data to the cloud using industrial IoT gateways
- In the application, gateways communicate with PLC systems through Modbus, collect field data, and upload information to a cloud dashboard for monitoring — bridging existing SCADA assets to modern cloud visibility rather than replacing them outright
Case Studies
Cloud-Connected Utility SCADA
26 Jun 2026Industrial IoT gateways for moving water and power utility SCADA data from PLCs, RTUs, and IEDs to cloud dashboards.
Overview
ChallengesThe main challenges were
- The utility had to improve reliability while retaining as much of its legacy SCADA equipment as possible
- The water side needed communication with PLC systems, RTUs, and IEDs, while the power side needed to replace legacy SCADA systems entirely and track over 3,000 data points
- The system also needed wireless communication, common industrial protocol support, and dependable operation across genuinely varied utility environments
ObjectivesThe system needed to
- Create a bridge between existing SCADA assets and cloud monitoring
- The gateway layer needed to collect data from PLCs and field devices, support Modbus and other industrial protocols, communicate through cellular networks, and let each department monitor information through its own customized dashboard
Solution DeliveredThe solution included
- An industrial IoT gateway was installed as the field communication node, collecting PLC and SCADA data locally and communicating out through a cellular module and SIM card to a cloud dashboard — a genuinely useful design where sites without fixed connectivity weren't left out of the modernization
- The same gateway family supports protocols including DNP3, Modbus RTU/TCP, OPC, and SNMP, and can communicate directly with RTUs, IEDs, and central computers, which is what let the utility connect its water-side PLC/RTU/IED assets and its power-side legacy SCADA (tracking over 3,000 data points) through the same gateway platform rather than needing separate integration projects for each side of the utility
Conclusion
Utility modernisation without replacing everything at once, but safely moving critical SCADA data from field infrastructure into cloud-based visibility. A practical and high-value power-sector transformation story.
